Definition[Bearbeiten]
The Musculi lumbricales pedis are four short, fleshy muscles that belong to the short foot musculature.
Course[Bearbeiten]
Origin[Bearbeiten]
The lumbricales pedis muscles originate from the tendons of the flexor digitorum longus muscle. The 1st muscle has its origin on the medial side of the tendon of the 2nd toe. The 2nd, 3rd and 4th muscles originate from the medial and lateral sides of 2 neighbouring tendons.
Attachment[Bearbeiten]
The short tendons of the muscles each pull towards the medial side of the corresponding toe and attach to the tendon extensions of the extensor digitorum longus muscle at the level of the proximal phalanx of the 2nd-5th toe.
Innervation[Bearbeiten]
The innervation of the two lateral lumbrical muscles (4th and 5th toe) is provided by the lateral plantar nerve (segments: S1 and S2). The two medial lumbrical muscles (2nd and 3rd toe) are innervated by the medial plantar nerve.
Function[Bearbeiten]
The lumbrical muscles cause flexion (bending) and adduction (bringing forward) of the toes in the metatarsophalangeal joints.
